Product details
Overview
TLV2472CP from Texas Instruments is a dual-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-power, high-output-drive applications. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and 250μV typical input offset voltage across 2.7V–6V supply range - enabling precision signal conditioning in battery-powered sensor interfaces and portable medical devices.
For engineers reviewing the TLV2472CP datasheet, TLV2472CP pinout, TLV2472CP application, or TLV2472CP equivalent, key selection considerations include its dual-channel SOIC-8 package, shutdown-incompatible design (no SHDN pin), rail-to-rail swing capability, ultra-low quiescent current, and compatibility with single-supply data acquisition systems operating down to 2.7V.
Technical Context
The TLV2472CP implements a CMOS input stage with 2.5pA typical input bias current and rail-to-rail input common-mode range (0V to VDD), supporting full dynamic range in low-voltage systems. Its output stage delivers ±35mA into loads while maintaining 180mV rail-to-rail swing under 10mA load, distinguishing it from legacy micropower op-amps.
It operates across –40°C to +125°C (I-suffix) or 0°C to +70°C (C-suffix); the CP suffix confirms the plastic DIP (PDIP-8) package and commercial temperature grade. Unlike TLV2470/3/5 variants, TLV2472CP lacks shutdown functionality - verified by absence of SHDN pin in its SOIC-8 and PDIP-8 pinouts and omission from shutdown-capable device table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables compact two-stage amplification or differential signal processing without discrete pairing. |
| Supply Voltage Range | 2.7V to 6V - supports direct operation from single Li-ion, 3.3V, or 5V rails without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - sufficient for anti-aliasing filters, sensor amplification up to ~200kHz closed-loop bandwidth. |
| Input Offset Voltage | 250μV (typ) - ensures ≤0.5mV error in 2V full-scale 12-bit systems without trimming. |
| Output Drive | ±35mA at 500mV from rail - drives 100Ω loads directly, eliminating external buffers in DAC output stages. |
| Supply Current per Channel | 600μA - enables 10+ hour battery life in continuous-sensing nodes powered by CR2032 cells. |
| Input Bias Current | 2.5pA - preserves signal integrity in high-impedance pH or photodiode front-ends. |
Pinout & Package
TLV2472CP uses an 8-pin plastic DIP (PDIP-8) package with 0.3-inch width, through-hole mounting, and industry-standard pin spacing. Pin 1 is marked by beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | Accepts feedback signal; high-impedance CMOS node (2.5pA bias) minimizes loading on RC networks. |
| 2 | Non-Inverting Input (Channel 1) | High-Z input for reference or sensor connection; rail-to-rail common-mode range (0V to VDD). |
| 3 | Output (Channel 1) | Delivers ±35mA at 500mV from rail; capable of driving 100Ω loads directly. |
| 4 | GND | Analog ground reference; must be star-connected to minimize noise coupling between channels. |
| 5 | Non-Inverting Input (Channel 2) | Independent high-Z input; no crosstalk with Channel 1 per datasheet crosstalk graph (Fig. 26). |
| 6 | Inverting Input (Channel 2) | Feedback node for second amplifier; matched input characteristics to Pin 1. |
| 7 | Output (Channel 2) | Fully independent output; supports simultaneous dual-sensor readout without interaction. |
| 8 | VDD | Positive supply rail; accepts 2.7V–6V; PSRR >66dB ensures immunity to digital supply noise. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2472CDR | Same electrical specs, but in SOIC-8 tape-and-reel packaging; no PDIP option. | Preferred for automated SMT assembly; incompatible with through-hole prototyping or legacy PDIP footprints. | Select TLV2472CDR for volume production PCBs using surface-mount processes. |
| OPA2340UA | Higher 5.5MHz GBW, 200μV offset, but 750μA/channel supply current; SOIC-8 only. | Better for higher-speed filtering (e.g., ultrasonic sensing), but increases power budget by 25%. | Choose OPA2340UA when bandwidth >2.8MHz is required and 150μA extra per channel is acceptable. |
Compared with TLV2472CP, TLV2472CDR offers identical performance in a surface-mount format ideal for modern manufacturing, while OPA2340UA trades 25% higher supply current for +96% bandwidth - making TLV2472CP optimal for cost-sensitive, battery-constrained dual-channel precision applications where 2.8MHz suffices.

FAQ
What is the maximum operating temperature range for TLV2472CP?
The TLV2472CP is rated for 0°C to +70°C (commercial temperature range), as indicated by the "C" suffix in the part number. It is not qualified for extended industrial or automotive temperature grades - those require the TLV2472IP (–40°C to +125°C) variant. Always verify ambient and junction temperature limits using the 104°C/W θJA value for PDIP-8 in thermal design.
Does TLV2472CP include a shutdown feature?
No, TLV2472CP does not include a shutdown feature. The TLV2472 device variant lacks a SHDN pin entirely - confirmed by its pinout diagram (8-pin PDIP with pins 1–8 assigned to IN−/IN+/OUT/GND/IN+/IN−/OUT/VDD) and explicit exclusion from the "shutdown-enabled" family members (TLV2470/3/5) in the datasheet's feature table and package table.
What is the typical input offset voltage of TLV2472CP and how does it affect 12-bit ADC interfacing?
The TLV2472CP has a typical input offset voltage of 250μV, with a maximum of 2400μV over temperature. When interfacing with a 2.5V full-scale, 12-bit ADC (LSB = 610μV), this offset contributes ≤0.4 LSB error at room temperature - well within acceptable bounds for uncalibrated systems. For tighter accuracy, offset nulling or software correction is recommended.
Can TLV2472CP drive a 100Ω load while maintaining rail-to-rail output swing?
TLV2472CP delivers ±35mA output current at 500mV from each rail, meaning it can sustain 5V output swing into a 100Ω load (requiring 50mA) only if the output is allowed to drop 500mV - i.e., VOH = 4.5V and VOL = 0.5V. For true rail-to-rail (≤180mV drop) operation, max load is ~10mA. Designers must choose between full swing or full current based on system requirements.
Is TLV2472CP pin-compatible with other dual op-amps in PDIP-8 packages like LM358 or MCP602?
No, TLV2472CP is not pin-compatible with LM358 or MCP602 in PDIP-8. While all are 8-pin dual op-amps, TLV2472CP uses standard dual-amplifier pinout (1: Ch1−, 2: Ch1+, 3: Ch1Out, 4: GND, 5: Ch2+, 6: Ch2−, 7: Ch2Out, 8: VDD), whereas LM358 swaps Ch2+ and Ch2− (pin 5 = Ch2Out, pin 6 = Ch2−), and MCP602 uses different assignments. PCB layout must follow TLV2472CP-specific pinout.
